METHOD OF SUSPEND'ING ELECTRIC." LIGHTS.

SPECIFICATION forming part of Letters Patent No. 355,443, dated January 4, 1887.

Application filed May 7, 1886. Serial No. 201,444. (No model.)

To all whom it may concern:

Be it known that I, HENRY F. EDWARDS, a citizen of the United States, residing at Providence, in the county of Providence and State 5 of Rhode Island, have invented certain new and useful Improvements in Methods of Suspending Electric Lights; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention has for its object to provide a novel means for suspending electric lights over the center'of a street or square, whereby the electric lamp may be maintained in the desired position between the two sides of the street, or drawn back to one side thereof for the renewal of the carbons or for necessary repairs, the construction being such that the lamp and its operative mechanism are protected from the direct action of the elements, and the lamp rendered easy of access at all times; and my invention consists, essentially, of the details of construction and general arran gement of parts, as will be hereinafter fully described, and specifically designated in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of a structure embody the principle of my invention; Fig. 2, atop plan view of the same, and Figs. 3 to 8 detail views thereof.

Similar letters of reference occurring on the several figures indicate like parts.

In carrying out my invention the truss or structure intended to span the street or square may be made of any suitable material and of the desired shape, but is preferably composed of a light iron truss, as represented in the drawings. At each end of said truss. and between its side pieces, A A, are placed eyebolts a and a hollow pipe, I), through which a bolt, 0, is passed'to securethe parts together to provide'a ready and convenient means for attaching the truss to the top of the poles B, or to the sides or tops of buildings. Upon 50 each inner side of the truss, and rigidly secured to the struts thereof, is provided an angle-iron mantled at any point.

frame, d, upon the lower portion of which the angle-iron track, e, is secured.

The carriage for carrying the lamp 0 is preferably composed of a light square frame-work, 5 5 g, secured to the central parts of four pendent rods or hangers, h, the upper ends of which in their turn are provided with flanged wheels i, adapted to move upon the tracks 6, while their lower ends are suitably secured to the hood or upper part, 70, of the lamp, as fully shown in Figs. 3 and 4 of the drawings. Directly above the wheels i, and rigidly secured to the frame d, is provided an overhanging cover or frame, f, which serves not only to protect the wheels and track from snow or ice,'but also effectually prevents the wheels from leaving the track, thereby obviating all danger of the carriage or lamp becoming blocked or dis- At the extreme outer end of the tracks 6 are provided suitable blocks 6', for stopping the lamp-carriage at that point, While a suitable pulley, 0 is provided for the reception of the outer portion of the rope Z, which moves said lamp-carriage back and forth, the upper portion of said rope preferably running freely within an inclosing pipe or tube, while the lower ends are secured to the carriage-frame g, as fully shown in Fig. 3.

Upon the upper portion of one of the poles B is provided a suitable pulley, m, over which the rope l passes within convenient reach ofthe attendant who cleans and repairs the lamp, a suitable stand or support, a, being provided near the upper part of said pole for his reception, and which is accessible by means of thefoot-irons 0 upon the post, as fully shown in Fig. 1.

Although the truss or framework may be secured in position to span a street or square outwardly from the lower part of the cap B- center of a street or square, .or over the centers of two streets crossing each other, and at the same time serves the additional purpose of a general carrier for wires of all kinds.

Having thus described'myinvention, I claim as new and usefu1 1. The herein-described truss or structure for suspending electric lights across streets or squares, consisting of the truss adapted to be secured at each end to buildings or poles, and provided with a covered track for the reception of a carriage for the electric lamp, substantial] y as specified.

2. A truss or structure for suspending electric lamps, consisting of the metallic truss provided with a covered track, a carriage for the electric lamp, and means for operating the same, and a series of insulated arms for carrying the wires, substantially as and for the purpose specified. v

3. In a truss or structure for suspending electric lights, the covered track 6, lamp-carriage g, lamp 0, pulleys e and m, and rope I, substantially as specified.

4. In a devicefor suspending electric lights, the poles B, provided with caps B, having aflixed thereto the arms B, having openings for the reception of the bolts a upon the ends of the truss or frame to secure the same in position, substantially as specified.

5. In a truss for suspending electric lights, the poles B, provided with cap EB, having affixed thereto the arms B, for the reception of the ends of the truss, pulley m, for the inner end of the rope l of the carriage-frame, and

the arms B, for carrying the wires, substan-.

tially as specified. I

In testimony whereof Iaffix my signature in presence of two witnesses.

. HENRY F. EDWARDS.
